The effect of trench patches and service covers on pavement management

This report describes the results of the project commissioned to investigate the effects of trench patches and service covers on pavement management. The main objective was to identify the effects of poorly reinstated and defective service covers on pavement management, in terms of pavement deterioration and pavement strength, and to recommend procedures to remedy the detrimental effects of trenches and service covers on pavement performance. A comprehensive system was developed for inventory and condition data of trenches and covers. Preliminary guidelines were developed for visually assessing the condition of trenches and covers. A deflection survey was undertaken to determine the effect of trenching on pavement and strength characteristics. Roughness was selected for detailed comparison of condition and performance of trench and trench-free sections. The difference in the cost of maintaining the road network due to the presence of trenches and covers was determined. Also, the change in the maintenance regime and the effects on pavement and surface lives were estimated. It was found that poor reinstatement decreases pavement performance and life. (a)
